Title: Method of producing coloured gelatine layers
IPC: G03C7/28
Filed: 1936-06-22
Abstract: 478,735. Colouring photographic imagebearing layers. GASPAR, B. June 22, 1936, No. 17299. Convention date, June 21, 1935. [Class 98 (ii)] Image-bearing gelatin layers are coloured by incorporating therein a dyestuff precipitant at any stage in the preparation or treatment of the layer and treating the layer after exposure with a dye solution or, if the layer contains a dye-forming substance with a reagent effecting formation of the dye. The precipitant may be added to the gelatin before pouring or the formed layer bathed in a solution of the precipitant and may be added in such amount as is necessary to precipitate the desired quantity of dye. The process allows of selectively dyeing superimposed layers by the use of selectively acting precipitants or of successive dye solutions, the first of which reacts with the precipitant in the first layer only. Alternatively, the precipitant for the lower layer may be added before pouring and that for the upper layer after colouring of the lower layer. Examples are given of (1) a silver bromide emulsion sensitized, e.g. with pinacyanol and coloured yellow with 2 - phenyl - 4 - aminoquinoline hydrochloride and Metanil Yellow. This is coated with a colourless layer of silver bromide emulsion containing diphenylguanidine acetate which is dyed after exposure, development and fixing with Diamine Pure Blue FF ; (2) on a yellow layer as in (1) a colourless silver bromide layer is applied and after development and fixing is treated with # - naphthoquinolinium - N - ethyl acetate and dyed with Diamine Pure Blue FF ; (3) a silver bromide emulsion is coloured with Chlorantine Light Yellow and barium nitrate and a colourless silver bromide emulsion containing cinchonone hydrochloride applied and dyed after exposure with Diamine Pure Blue or Diamine Fast Pink BBF ; and (4) a silver halide layer containing sodium salicylate is coated with a layer containing Diamine Pure Blue and triphenyl-guanidine acetate and after exposure is additionally dyed with Auramine. The dyes may be selectively destroyed in the presence of the silver by acid thiocarbamide solution. As precipitants for acid dyes in addition to the above, quinine, aminoquinoline, barium carbonate, and magnesium carbonate may be used and for basic dyes zinc ferrocyanide, antimony salts or tannic acid. Dye intermediates such as leuco compounds may be used in place of dyes. Specifications 397,159, 415,756. and 428,158 are referred to. The Specification as open to inspection under Sect. 91 comprises also the application of the dyes to the layer prior to exposure, and an example in which #-naphthoquinolinium.N- ethyl sulphate is added to a solution of gelatin and the layer formed therefrom dyed with Diamine Pure Blue FF. This subject-matter does not appear in the Specification as accepted.

Patent GB-1005397-A (GB)
Title: Process for the manufacture of alumina
IPC: C01F7/144
Filed: 1962-05-04
Abstract: Alumina trihydrate is obtained by the Bayer process in which precipitation from sodium aluminate solution is effected by means of seed crystals of the products, this process being modified in that active acid crystals and fines having a smaller particle size than the final product are used.  The mixture is stirred to increase agglomeration of the alumina trihydrate. The active seed crystals are prepared by introducing alumina trihydrate into a sodium aluminate solution at a temperature causing the formation of crystalline flakes on the surface of the alumina trihydrate, allowing the flake to grow forming microcrystals which themselves become nuclei for precipitation.
